What is hybridization?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals, which are used to form covalent bonds in molecules.

What type of alloy is formed when the atomic radii of the components are similar?

Back

Substitutional alloy.

Front

Define covalent bond.

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs.

Front

What is the significance of bond angles in molecular geometry?

Back

Bond angles help determine the shape of a molecule, which affects its reactivity and properties.

Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.
